Pants kicking is over, let’s do serious economics now

Comment on Lars Syll on ‘Solow kicking Lucas and Sargent in the pants’

Clearly, the description is spot on and it holds for Walrasianism, Keynesianism, Marxianism, Austrianism. Everybody knows by now that economics is a failed science. The lack of sound theoretical foundations, though, has never stopped an economist from giving his scientifically worthless economic policy advice.

The question of the aspiring student is: Given that economics is a failed science, I am not so much interested in who messed up what in the last 200+ years, or whether the incompetence has been greater in Chicago than in Cambridge, what I need to know is how the actual economy works. So, do not waste more time with pants kicking, tell me what the fatal mistake/error/blunder is and how to get over it.

Here is ― for the last time ― the bone of contention: “The purported strength of New Classical macroeconomics is that it has firm anchorage in preference-based microeconomics, and especially the decisions taken by inter-temporal utility maximizing ‘forward-looking’ individuals. To some of us, however, this has come at too high a price. The almost quasi-religious insistence that macroeconomics has to have microfoundations ― without ever presenting neither ontological nor epistemological justifications for this claim ― has put a blind eye to the weakness of the whole enterprise of trying to depict a complex economy based on an all-embracing representative actor equipped with superhuman knowledge, forecasting abilities and forward-looking rational expectations. It is as if ― after having swallowed the sour grapes of the Sonnenschein-Mantel-Debreu-theorem ― these economists want to resurrect the omniscient walrasian auctioneer in the form of all-knowing representative actors equipped with rational expectations and assumed to somehow know the true structure of our model of the world.” (See intro)

In brief, Walrasian microfoundations are false. Methodologically, the iron law applies: Because the axiomatic foundations#1 are false the whole analytical superstructure from constrained maximization to DSGE/RBC/New Keynesianism is false.

Unfortunately, Keynesian macrofoundations are false, too.#2 So, there is NO valid economics.

This is the current state of economics: Economists give policy advice without having a scientifically sound theory.#3 Economic theory is a failure because it has been based on methodologically unacceptable axiomatic foundations. Therefore, there is no way around a paradigm shift. In other words, the false Walrasian microfoundations and the false Keynesian macrofoundations have to go out of the window and have to be completely replaced by entirely new macrofoundations.#4

There is no other way out of the scientific mess economics is in. As Hilbert put it: “The axiomatic method is indeed and remains the one suitable and indispensable aid to the spirit of every exact investigation no matter in what domain; ... To proceed axiomatically means in this sense nothing else than to think with knowledge of what one is about.”

Until this very day, neither Orthodoxy nor Heterodoxy got the basic economic concepts and their relations right. And this is why economics is still on the proto-scientific level of incoherent blathering with NO idea ‘of what one is about’.

How science is done is known since more than 2000 years ― except to economists: “When the premises are certain, true, and primary, and the conclusion formally follows from them, this is demonstration, and produces scientific knowledge of a thing.” (Aristotle) Because of this “... it can fairly be insisted that no advance in the elegance and comprehensiveness of the theoretical superstructure can make up for the vague and uncritical formulation of the basic concepts and postulates, and sooner or later ... attention will have to return to the foundations.” (Hutchison)

The new general rule to apply for economic research, discussion, peer-review and textbooks is: If it isn’t macro-axiomatized, it isn’t economics. This rule vaporizes roughly 99 percent of what has hitherto been accepted as economics. Forgetting all this proto-scientific rubbish enhances scientific productivity enormously.

The hybrid science

As a first approximation, one can agree on the general characteristic that the economy is a complex system.

However, with the term system one usually associates a structure with components that are non-human. In order to stress the obvious fact that humans are an essential component of the economic system the market economy should be characterized more precisely as a complex hybrid human/system entity or sys-hum.

The scientific method is straightforwardly applicable to the sys-component but not to the hum-component. While it is clear that the economy always has to be treated as an indivisible whole, for good methodological reasons the analysis has to start with the objective system-component.

In gestalt-psychological terms the economic system is the foreground, individual behavior the background. Common sense wrongly insists that the hum-component must always be in the foreground. This fallacy compares to Geo-centrism. The economic system has its own logic which is different from the behavioral logic of humans. The systemic logic is what Adam Smith called the Invisible Hand.

There are systemic laws but no behavioral laws. Systemic laws have the same methodological status as physical laws.

Neither Orthodoxy nor Heterodoxy can tell what the systemic laws of the actual monetary economy are.

Whether the outcome of the human/system-interaction is good or bad is a politcal question that lies outside of theoretical economics. Theoretical economics explains how the actual economy works - no less, no more.

Narrative vs.Theory

Psychological, sociological or behavioral assumptionism cannot yield anything other than a gossip model of the world. Second-guessing the agents is not economic analysis.

Storytelling is the original mode of communication in the social realm — except science.

Political economics is storytelling and, by default, the natural habitat of confused confusers. Walrasianism, Keynesianism, Marxianism, Austrianism are social narratives and not scientifically valid representations of reality.

"The truth is, most persons, not excepting professional economists, are satisfied with very hazy notions." (Fisher)

In marked contrast, theoretical economics lives up to the standards of material and formal consistency. A scientific theory is the best representation of reality that is humanly possible.

Paradigm shift

"The problem is not just to say that something might be wrong, but to replace it by something — and that is not so easy." (Feynman)

"As will become evident, there is more agreement on the defects of orthodox theory than there is on what theory is to replace it: but all agreed that the point of the criticism is to clear the ground for construction." (Nell)

"The moral of the story is simply this: it takes a new theory, and not just the destructive exposure of assumptions or the collection of new facts, to beat an old theory." (Blaug)

"The task of producing knowledge against the grain requires imagination." (Mirowski)

"A new idea is extremely difficult to think of. It takes a fantastic imagination." (Feynman)

"The scientific imagination dreams of explanations and laws." (Peirce)

"It is brilliance of imagination which makes the glory of science." (Evans)

"... we know little more now about ‘how the economy works,’ ... than we knew in 1790, after Adam Smith completed the last revision of The Wealth of Nations." (Clower)

The Starting Problem or What are your axioms?

"What are the propositions which may reasonably be received without proof? That there must be some such propositions all are agreed, since there cannot be an infinite series of proof, a chain suspended from nothing. But to determine what these propositions are, is the opus magnum of the more recondite mental philosophy."

To be replaced (1)

The core premises of Orthodoxy are uncertain and false and this fully explains the failure of the research program.

“As with any Lakatosian research program, the neo-Walrasian program is characterized by its hard core, heuristics, and protective belts. Without asserting that the following characterization is definitive, I have argued that the program is organized around the following propositions: HC1 economic agents have preferences over outcomes; HC2 agents individually optimize subject to constraints; HC3 agent choice is manifest in interrelated markets; HC4 agents have full relevant knowledge; HC5 observable outcomes are coordinated, and must be discussed with reference to equilibrium states.” (Weintraub)

This elementary syllogism is demonstrably false. The demonstration consists in the proof that Keynes could not solve the Profit Puzzle. Neither did Post-Neo-New-Keynesians.

In the most general terms, the economics paradigm shift consists in switching from the behavior-centric bottom-up approach to the structure-centric top-down approach. This is comparable to the Copernican turn from Geo-centrism to Helio-centrism.

Paradigm shift

Walrasianism, Keynesianism, Marxianism, Austrianism is provable false and this requires the shift to an entirely new paradigm

AXEC-Meme

If it isn’t macro-axiomatized, it isn’t economics.

Consensus

Economics is a science without scientists. Because they are ignorant of the elementary difference between profit and income, the present generation of economists has not made and cannot make a significant contribution to the discussion about how the actual economy works.

Every orthodox or heterodox economist can convince himself/herself that their profit theory is defective.

Because the profit theory is false the whole of conventional economic theory has to be rejected.

"What is now taught as standard economic theory will eventually disappear, no trace of it will remain in the universities or boardrooms because it simply doesn’t work: were it engineering, the bridge would collapse." (McCauley)

No scientist will ever accept Walrasianism, Keynesianism, Marxianism, or Austrianism. These approaches are logically and/or empirically refuted. This is the actual methodological state-of-the-art. Walrasians, Keynesians, Marxians, or Austrians are still at the proto-scientific stage. These approaches cannot be improved, only abandoned.

Economists are a public nuisance because they have an opinion on everything but knowledge of nothing.

Nopopop

This blog does not add to any popular/un- popular opinion.

This blog does not hand out advice about how to avoid taxes, to get rich on the stock market, to be successful in business, to increase the wealth of nations, to run an economy, to maximize welfare, to prevent national/global bankruptcy, to improve the institutional setup of society, to get out of national/global depression, nor about how to save humankind or any subgroup thereof.

This blog is about the true theory of the actual monetary economy.

"In order to tell the politicians and practitioners something about causes and best means, the economist needs the true theory or else he has not much more to offer than educated common sense or his personal opinion." (Stigum)

Redefining economics

Old definition, subjective-behavioral:

Economics is the science which studies human behavior as a relationship between ends and scarce means which have alternative uses.

New definition, objective-systemic:

Economics is the science which studies how the monetary economy works.

From proto-science to science

Political economics is scientifically worthless since more than 200 years

Focus

Science is of primary interest and importance. Scientists are of secondary interest. The general public finds it remarkable that one of Einstein’s peculiar habits was to never wear socks. In marked contrast, physicists find alone his field equations remarkable.

With regard to science most people lose focus easily because of a natural preference for anecdotes over facts or subjectivity over objectivity.

Hence, Schumpeter once considered it necessary to remind his habitually disoriented fellow economists: “Remember: occasionally, it may be an interesting question to ask why a man says what he says; but whatever the answer, it does not tell us anything about whether what he says is true or false.”

Caution: Do not expect a corroboration of your political view. Neither a refutation. Political economics has been scientifically worthless since Adam Smith. Politics has to be separated from economics because it is categorically different from science.The best science can do and has always done is to prove beyond reasonable doubt that you have been objectively wrong or ignorant until now. Science goes beyond the naive common sense of today and becomes the sophisticated common sense of tomorrow.

Motto

Outlook

To recall, while political economics is storytelling, theoretical economics adheres to scientific standards.

The first task of theoretical economics is to get the axiomatic foundations right. This is what J. S. Mill called the opus magnum. Neither Orthodoxy nor Heterodoxy came up with a reasonable solution until this day. This explains the secular stagnation of economics.

There is no serious alternative to structural axiomatic economics. This is not a matter of opinion but of proof. The sole criteria are material and formal consistency.

All truths are easy to understand once they are discovered; the point is to discover them.

Major economic policy implication

The price mechanism does not work as standard economics hypothesizes. The axiom-based employment equation states that overall employment increases if the average wage rate increases relative to average price and productivity. This gives one the lever to improve the employment situation all over the world and to fend off deflationwithout rising debt and without artificial capacity growth. To increase the average price relative to the average wage rate and productivity increases unemployment. This is what happens at the moment with the Fed's inflation goal.

Right policy depends on true theory.

“In order to tell the politicians and practitioners something about causes and best means, the economist needs the true theory or else he has not much more to offer than educated common sense or his personal opinion.” (Stigum)

Lacking the true theory, economists promote since more than 200 years opinion instead of knowledge.
